Flashing is metal or composite material installed at roof intersections, edges, and penetrations to channel water away. Unlike other roof parts, flashing takes direct impact from wind, rain and thermal shifts. Correctly installed flashing extends roof life by sealing vulnerable zones and preventing water ingress.
Leak prevention at junctions, walls and roof transitions
Protection of roof deck, rafters and interior structure
Compatibility with roof movement (expansion/contraction)
Low maintenance, long performance life
Site survey of all roof penetrations, transitions and edges
Design and selection of flashing type and profile
Pristine installation of step, kickout, valley, counter, and drip-edge flashings
Expert sealing of seams, overlaps and terminations
Integration with roofing membranes, underlays and cladding
Even top-tier roof materials fail if flashing isn’t installed correctly water will sneak in behind walls or through edges.
Metal and roof surfaces expand/contract. Flashing must accommodate that movement without tearing or opening.
Poor flashing detracts visually and can cause material deformation or staining as water diverges.
Quality flashing avoids repeated patching, underlying rot, and interior damage that comes from secondary leaks.
1. Junction Review & Planning
We map every intersection chimneys, walls, skylights, valleys and plan flashing layout and material.
2. Material Matching & Fabrication
We choose finishes (Colorbond®, galv steel, copper) and custom-bend flashing to match roof slopes and junctions.
3. Surface Prep & Flashing Foundations
Clean and dry where flashing mounts, remove old or worn materials, prepare substrates for adhesion.
4. Flashing Fitting & Alignment
Fit flashings in correct order (step, counter, valley, drip) with oversight on overlaps and flow direction.
5. Sealing & Junction Protection
Seal seams, nail holes, edges with high-performance sealant; integrate with roofing membranes and underlay.
6. Testing & Quality Assurance
Simulate water flow, inspect every seam, clean site, and issue warranty documentation for installed flashings.
Step Flashing — used where roof meets vertical walls or chimneys, ensuring water flows over flashing layers
Valley Flashing — protects and channels heavy runoff in roof valleys
Drip-Edge / Eaves Flashing — seals edge of roof to prevent seepage under roofing materials
Counter & Chimney Flashing — secures roof-wall junctions, preventing water behind wall surfaces
Kick-Out Flashing — directs water off walls into gutters, preventing staining or façade damage
Keep an eye out for:
Water stains or damp spots near walls or roof-wall joints
Flashing seams lifting, splitting, or gaps opening
Rust or corrosion visible on flashing panels
Flashing metal showing discoloration, bending, or separation
Active leaks near vents, skylights, chimneys, or wall junctions
Precision & Compatibility — our flashings are tailored to your roof’s slope, materials, and junction types.
Top-Grade Materials — we use robust flashing metals and coatings suited to Australian climate (corrosion-resistant, flexible).
Licensed & Insured Professionals — work is compliant with safety and building standards.
Transparent Approach & Trust — clear quotes, detailed scopes, and visible workmanship.
Strong Warranties & Aftercare — you get protection for both materials and installation quality.
Typically one to two days for a residential roof depending on number of penetrations, complexity, and access.
Yes, over time flashing may corrode, sealant degrades, seams open. When signs show, replacement is recommended.
Absolutely. Retrofitting flashing is common around added features like skylights or walls.
When installed properly and underlying roof conditions are sound, yes, flashing is vital for leak prevention.
Not always. In most cases flashing can be installed or replaced without removing large roof sections.
